That patch does nothing. I think he has a bug in the code. I will post on the tracker.
Regardless, even if you correct the patch, all he's doing is disabling deep color (36-bit) output. That won't matter for Kodi today because your frame buffer is 24-bit anyway. In the future if Kodi decides to use a 30-bit or higher frame buffer for HDR, etc. you will be faced with the same bug again. Better if Intel fixes this properly now.
Yes. It's a shortterm solution. The idea was: Don't run 36 bit if the framebuffer is 24 bit only. We will see. I would be happy to get a working version of this patch into kernel 4.7 stable - so that LE has that fixed. Perhaps some background: Currently the following happens: The 8 bit input is interpolated to 12 bpc and then later down dithered to the display - which I find quite suboptimal, especially in combination with kodi where we only output RGB 8 bit.
